Question

Quizplus · Accepted Answer

When an experiment has two independent variables, there will be two main effects (one for each independent variable) and one interaction effect between them. Therefore, the correct answer is C, which states that there are two main effects and one interaction. Option A is incorrect as it only considers one interaction and ignores the main effects. Option B is incorrect as it only considers one main effect and one interaction and ignores the other main effect. Option D is incorrect as it assumes two interactions, which may not always be present in an experiment with two independent variables.
